Lim Cheng Choo (Chinese: 林清注; pinyin: Lín Qīngzhù; Pe̍h-ōe-jī: Lîm Chheng-chù; 15 March 1905 – 31 December 1993)[2][3] was a prominent Bruneian aristocrat, politician, and business leader.

A staunch advocate for education, he was the longest-serving board member of Chung Hwa Middle School, Bandar Seri Begawan (CHMS, BSB), dedicating over five decades to its development and spearheading major fundraising initiatives.

At the age of ten, Lim moved to Brunei to live with his father, where he attended school while also helping out at Ong Boon Pang's shop, Teck Guan Company, for a salary of $3 a month.

Lim continued his education in China before starting work at Ong Boon Pang's Teck Guan Company at the age of sixteen.

Demonstrating impressive commercial acumen at a young age, he was allowed to handle the pawnbroker's firm, showcasing his early promise as a businessman.

[5] Throughout the Japanese occupation, Lim frustrated the occupiers by refusing to provide information about the company, which led to him being beaten and imprisoned for three days before securing his release with the help of a friend.

Lim remained actively involved with the board until his passing in 1993, making him its longest-serving member with a remarkable total of fifty-two years dedicated to the school's development and success.

On 7 January 1979, Lim was selected once again to represent Brunei in signing the " Treaty of Friendship on Co-operation," which ultimately paved the way for the nation's full independence in 1984.

[5] Furthermore, he was among five state dignitaries who attended the Melayu Raya Meeting in Kuala Lumpur from 6 to 8 January 1962,[7] further illustrating his commitment to the nation’s political landscape.

He believed that there was lots of open farmland that could be used to grow fruits and vegetables, and thus the country should lessen its reliance on foreign nations for its food supplies.

Even though he was becoming older, Lim stayed committed to his job and insisted on working three to four hours a day till his death in order to serve the Chinese community and his fellow citizens.
